Captive Portal Provider List

Last update : 7/3/2022

Introduction

Just a minor list of captive portal providers.

Recommended

These are the ones I can safely recommend, unless you have a reason not to use them.

/e/

The default connectivity checker for /e/ OS, hosted at Scaleway, Netherlands. Not as reliable as the other checkers in my experience.

Connectivity check URLs :

• HTTP : https://204.ecloud.global
• HTTPS : https://e.foundation/net_204/
• Fallback : use HTTP / HTTPS above. Do be aware that if you're using /e/ Pie/Oreo/Nougat, it defaults to http://www.google.com/generate_204.
• Other fallback : use HTTP. Do be aware that if you're using /e/ Pie/Oreo/Nougat, it defaults to http://play.googleapis.com/generate_204.

Connectivity check IP : 51.91.138.20 (IPv4)

Graphene

The default connectivity checker for GrapheneOS, unless you've toggled the connectivity check setting to use Go-ogle's servers. Pretty reliable in my personal experience, but this is one of the longer ones to type in.

Connectivity check URLs :

• HTTP : http://connectivitycheck.grapheneos.network/generate_204
• HTTPS : https://connectivitycheck.grapheneos.network/generate_204
• Fallback : http://grapheneos.online/gen_204
• Other fallback : http://grapheneos.online/generate_204

Kuketz

A connectivity checker owned & provided by Mike Kuketz, a German security researcher. So far, this is the connectivity checker I use the most, since it's the most reliable (and also the least bothersome to type in).

Connectivity check URLs :

• HTTP : http://captiveportal.kuketz.de
• HTTPS : https://captiveportal.kuketz.de
• Fallback : use HTTP / HTTPS
• Other fallback : use HTTP

Connectivity check IP : 185.163.119.132 (IPv4)

Avoid

Ones you must avoid for various reasons, such as privacy invasive, questionable trustworthiness, questionable uptime, etc.

Google

The default captive portal provider for literally every ROMs except for a select few (/e/ default, Graphene default).

Connectivity check URLs (in case you'd like to block them) :

• HTTP : http://connectivity.gstatic.com/generate_204
• HTTPS : https://www.google.com/generate_204
• Fallback : http://www.google.com/generate_204
• Other fallback : http://play.googleapis.com/generate_204
